Title: Multi-carrier transmitter and receiver
Inventor: TOUKADO TETSUO
IPC: H04B1/707
Filed: 1995-04-26
Abstract: PURPOSE: To reduce the effect of fading by adding an error correcting code to input information, distributing the information to each channel, and respectively subjecting each information to spread spectrum, different frequency modulation, synthesis and transmission. CONSTITUTION: An 8-bit signal added to 8-bit input serial information from a terminal A1 by an error correction coding circuit 1 is converted into 1-bit for each channel by a serial/parallel conversion circuit 2. Then spread spectrum devices 3-1 to 3-n apply spread spectrum modulation using BPSK to the resulting signal. Then the data are mixed at an oscillating frequency different by a frequency corresponding to a data speed B, for example, and superimposed on a subcarrier by frequency modulators 6-1 to 6-n. The frequency interval of the subcarrier is basically made close up to an interval demodulated where each spectrum is not interfered and allocated to a frequency interval corresponding to the data speed B of each subcarrier. Modulated waves are synthesized by a synthesizer 7 and the result is outputted as a synthesis transmission signal.

Abstract: PURPOSE:To drive an ultrasonic motor efficiently by increasing an elastic modulus with separation from the contact surfaces of a stator and a rotor in the direction of the central axis of revolution of a ring in a ring-shaped elastic body section in the stator. CONSTITUTION:A stator 1 for an ultrasonic motor is composed of a ring-shaped elastic body 2 and a piezoelectric element 3, and a rotor 5 is pressure-welded to the elastic body 2.

Title: Temperature controller
Inventor: IKEHARA TAKASHI
IPC: G05B11/36
Filed: 1982-06-14
Abstract: PURPOSE:To increase a temperature rising speed and to perform uniform heating, by turning on a switching element at a 100% conduction angle up to specific temperature and then at a conduction angle corresponding to set temperature thereafter. CONSTITUTION:A pulse signal synchronizing with the zero crossing of an AC power source is led out of the collector of a transistor TR11 in the early stage of electric conduction and induced by a pulse transformer 63 to be applied as a gate signal to a TRIAC, which conducts at the 100% conduction angle to allow a heater 2 to consume 100% electric power, so that the temperature rises speedily. Once the temperature attains to self-holding resetting temperature, a base current is applied to a TR49, which then turns on and turns off because a base signal by-passes it, resetting a self-holding operation. When the temperature attains to the set temperature set by a volume control 23, the TRIAC3 turns on at the conduction angle corresponding to the temperature and a self-holding circuit holds the set temperature in this state.

Title: Setting unit for remote monitoring control system
Inventor: YATEMATA TAKESHI
IPC: H04Q9/00
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To facilitate the recognition of a setting content and to easily detect erroneous settings by referring to relation data stored in a storage means and displaying an identifier using the designated address on a display part, when the address of the terminal unit of a load-side is designated by an operation part. SOLUTION: A central processing unit gives identifiers to respective groups in the corresponding relation of addresses between respective switches and loads and stores relation data. When an operation part 13 designates the address of the terminal unit on a load-side, all the identifiers using the designated address are discriminated from the identifiers which can be used and which are not used, and they are displayed on a display part 12. When a load which is not a control object operates at the time of collective control such as pattern control and group control, the address of the load is designated and the identifier (a pattern number and a group number) are obtained. Thus, erroneous setting can easily be detected and therefore site adjustment in pattern setting and group setting can easily be executed.
